Kondratyuk S.Y., Lőkös L., Kondratiuk A.S., Kärnefelt I., Thell A., Farkas E. & Hur J.-S. (2022): Contributions to molecular phylogeny of lichens 3. New monophyletic branches of the Trapeliaceae and Xylariaceae [sic!], Acta Botanica Hungarica, 64: 97–135

Seven new genera, i.e. Brianiopsis for the former ‘Lambiella’ impavida group, Farkasiella for the former ‘Trapeliopsis’ aeneofusca group, Gallowayiopsis for the former ‘Trapelia’ collaris group, Kleopowiella for the former ‘Trapelia’ placodioides group, Trapegintarasia for the former ‘Trapelia’ lilacea group, Trapejamesia for the former ‘Trapelia’ corticola branch, as well as Xyloelixia for the former ‘Xylographa’ isidiosa group are proposed. Isolated position of ‘Lambiella’ … Read more...

Tanona M. & Czarnota P. (2022): Do the natural dynamics of West Carpathian forests affect the diversity of epiphytic lichens on Norway spruce?, Acta Oecologica, 115: 103830 [11 p.]

Over the last decades the West Carpathian spruce and mixed forests with a share of Picea abies, have been undergoing intensified dynamic changes, determined by windstorms and European spruce bark beetle outbreaks. Those changes should have a decisive effect on the survivability of species and shifts in epiphytic lichen communities on this phorophyte. Research conducted in the Gorce Mts (West Carpathians, Poland) in 1993, 2013 and 2018, on the same 186 spruce trees at 33 sites, revealed an increase … Read more...

Gerasimova J.V., Beck A., Werth S. & Resl P. (2022): High diversity of Type I polyketide genes in Bacidia rubella as revealed by the comparative analysis of 23 lichen genomes, Journal of Fungi, 8(5): 449 [26 p.]

Fungi involved in lichen symbioses produce a large array of secondary metabolites that are often diagnostic in the taxonomic delimitation of lichens. The most common lichen secondary metabolites—polyketides—are synthesized by polyketide synthases, particularly by Type I PKS (TIPKS). Here, we present a comparative genomic analysis of the TI‐PKS gene content of 23 lichenforming fungal genomes from Ascomycota, including the de novo sequenced genome of Bacidia rubella. Firstly, we identify … Read more...

Denchev C.M., Shivarov V.V., Denchev T.T. & Mayrhofer H. (2022): Checklist of the lichenized and lichenicolous fungi in Bulgaria, Mycobiota, 12: 1–106. doi: 10.12664/mycobiota.2022.12.01

A checklist of all taxa of lichenized and lichenicolous fungi recorded from Bulgaria is presented. The lichen biota as currently known includes 1137 taxa (1115 species, 5 subspecies, and 17 varieties) of lichenized fungi, 46 species of lichenicolous fungi, and 28 non-lichenized fungi traditionally included in lichenological literature. Lepra corallina is reported for the first time from Bulgaria. An index of synonyms based on literature records from Bulgaria is appended. It includes 1761 … Read more...

Kaufmann M. (2022): Flechtenvegetationskundliche Momentaufnahmen an einem unreifen, karbonatisch zementierten Quarzsandstein (Reiselsberg-Formation; Vorarlberger Flysch) in unterschiedlichen Verwitterungsstadien, mit einem Seitenblick auf die ökologische Standortskonstanz, inatura – Forschung online, 99: 1–63

Das Hauptaugenmerk der flechtensoziologischen Untersuchungen am Reiselsberger-Sandstein der Flyschzone Vorarlbergs galt dem Gesteins-Chemismus, der durch das Verwitterungsgeschehen geprägt ist. Trotz Dominanz von Quarz zeigt der verwitternde Sandstein aufgrund des gelösten carbonatischen Bindemittels die Charakteristika eines Intermediärgesteins. Bearbeitet wurden großflächige, mehr oder weniger steilgestellte Felsplatten, die an Steilabhängen anstehen oder an Felsabbrüchen und Felsgraten … Read more...

Tunç E. & Çetindemir B. (2022): The effect of lichens on soil aggregate stability, International Journal of Energy and Engineering Sciences, 7(1): 40–51

This study was carried out to investigate the effect of lichens on soil aggregate stability. In the study, lichen and non-lichen soil samples were taken from the forest areas of the Meulenwald region of Germany, consisting of Picea abies (L.) and Pinus sylvestris (L.) species, where lichens of Cladonia furcata, Cladonia coniocraea, Peltigera rufescens and Baeomyces rufus were detected. In this study, soil samples were evaluated in terms of soil pH, organic matter (%) content, soil permeability, texture … Read more...

Koch N.M., Stanton D., Müller S.C., Duarte L., Spielmann A.A. & Lücking R. (2022): Nuanced qualitative trait approaches reveal environmental filtering and phylogenetic constraints on lichen communities, Ecosphere, 13(4): e4042 [14 p.]

We propose that a qualitative trait approach based on more detailed nuanced traits may reveal previously overlooked patterns, especially when combined with phylogenetic perspectives. By sampling epiphytic lichens and using a functional approach based on nuanced qualitative traits, such as a much greater resolution over photobiont identity, type of cortex, and chemical compounds, we evaluated the effects of environmental filtering and phylogenetic constraints on community assembly along a natural … Read more...

Aigner S., Arc E., Schletter M., Karsten U., Holzinger A. & Kranner I. (2022): Metabolite profiling in green microalgae with varying degrees of desiccation tolerance, Microorganisms, 10(5): 946 [18 p.]

Trebouxiophyceae are microalgae occupying even extreme environments such as polar regions or deserts, terrestrial or aquatic, and can occur free-living or as lichen photobionts. Yet, it is poorly understood how environmental factors shape their metabolism. Here, we report on responses to light and temperature, and metabolic adjustments to desiccation in Diplosphaera epiphytica, isolated from a lichen, and Edaphochlorella mirabilis, isolated from Tundra soil, assessed via growth and photosynthetic … Read more...

Do T.-H., Duong T.-H., Nguyen H.T., Nguyen T.-H., Sichaem J., Nguyen C.H., Nguyen H.-H. & Long N.P. (2022): Biological activities of lichen-derived monoaromatic compounds, Molecules, 27(9): 2871 [11 p.]

Lichen-derived monoaromatic compounds are bioactive compounds, associated with various pharmacological properties: antioxidant, antifungal, antiviral, cytotoxicity, and enzyme inhibition. However, little is known about data regarding alpha-glucosidase inhibition and antimicrobial activity. Very few compounds were reported to have these activities. In this paper, a series of monoaromatic compounds from a lichen source were isolated and structurally elucidated. They are 3,5-dihydroxybenzoic acid (1), … Read more...

Bui V.-M., Duong T.-H., Chavasiri W., Nguyen K.-P.-P. & Huynh B.-L.-C. (2022): A new depsidone from the lichen Usnea ceratina Arch [sic!], Natural Product Research, 36(9): 2263–2269

Chemical investigation of the lichen Usnea ceratina Arch led to the isolation of five depsidones, including one new compound ceratinalone (1) along with four known compounds bailesidone (2), stictic acid (3), 80-O-methylstictic acid (4) and 80-O-ethylstictic acid (5). The structures were determined by analysis of their MS and NMR data as well as by comparison with literature values. Compounds 1 and 4 were evaluated the cytotoxic activity against HeLa (human epithelial carcinoma), NCI-H460 … Read more...
